Thank you for the insightful answer. Yes, I realize I have been taking the existence of a gravitational field for granted, without really thinking about the underlying mechanism - i.e. GR and the curvature of space-time according to latest theory. I had thought my simple argument involving the...

My understanding of electromagnetic radiation is this: When a charged particle accelerates, there is a change in its associated electric field at all points in space, though not instantaneously. The "electric field wave" is basically the propagation of the disturbance that occurs when the...

The equations are correct now. But as the other poster mentioned, your introduction of significant figures has caused your final answer to be imprecise. The exact values for I1 is 0.666666... (i.e. 2/3), and the exact value for I3 is 0.1666666... (i.e. 1/6). I would suggest using the fraction...

The person who touches the cable while standing on the ground will be electrocuted IF by touching the wire, he forms a complete circuit from the cable via his body, through the ground and back to the voltage source. It is common for one side of a power system to be electrically connected to the...

Fair enough, makes sense. Thanks!

It looks like the second equation you wrote for Kirchhoff's law around the left-hand side loop has an error. It should be 10 - 12 * (I1) - 4 * (I2) = 0, but you have a coefficient of 16 in front of I1. Also, it looks like the terms in the third equation were also summed up incorrectly - the...

Hey, you're right - I did! How brilliant!

If your school offers it, you could take AP Physics B, which is non-calculus based (Algebra 2 and Pre-calc will more than suffice for this class). AP Physics B will not fulfill any of the physics requirements in college if you major in physics, but at least it will give you an idea if this is a...

Hello, My question is about accelerating charges generating electromagnetic radiation, and is more of a theoretical one, or a thought-experiment in my head...probably because I'm not totally understanding something. I was playing with this applet which simulates the electric field lines of a...

These are all very helpful and great responses. Thank you very much.

Hello, I am taking an introductory course in quantum mechanics. One thing I am confused about is, Schrodinger's equation seems to be regarded as the "ultimate" formula which determines a particle's possible wavefunctions and energies, given a certain potential (Hamiltonian of psi = Energy...
